(1) Where the purchase is a commercial transaction for both parties, the buyer is to inspect the goods promptly after delivery by the seller, insofar as this is practicable in the ordinary course of business, and is to notify the seller without undue delay if a defect becomes apparent.
(2) If the buyer fails to notify the seller, then the goods are considered to have been approved, unless the defect is one which was not apparent on inspection.
(3) Where such a defect becomes apparent later, notification must be made promptly as soon as the discovery is made; otherwise the goods are considered to be approved also considering such defect.
(4) Timely dispatch of the notification suffices to preserve the buyer’s rights.
(5) If the seller has fraudulently concealed the defect, then the seller cannot rely on these provisions.
